To all whom it my concern: 7

Be it known that I, ALBERT W. HEINLE,

' residing at Crafton, Allegheny county,

Pennsylvania, have invented a new and useful Improvement in Methods and. Apparatus for Making Speciallyeshaped Bars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a plan view partly broken away of one form of rolling mill which may be employed in carrying out my invention;

Fig. 2 is a sectional elevation of the same;

Fig. 3 is an elevation of one set of the rolls employed, with the necks thereof broken away;

Fig. 4 is a similar view of the second set of rolls;

Figs. 5 and 6 are views of the shaping collars employed as a part of the rolls shown in Figs. 3 and 4, respectively;

Figs. 7, 8, 9 and 10 are fragmentary views of four sets of rolls which may be used in carrying out the invention and with the blanks shown in section in the several roll passes; I

Fig. 11 is a perspective View of a portion of one of the finished shaped bars;

Fig. 12 is a plan view; and Fig. 13 an end View of the twisting guide; and a Fig. 14 is a plan view partly broken away of one, of the roll bodies shown in Figs. 3 and 4:.

My invention has relation to the manufacture of specially. shaped bars, and is designed to provide a method and means by which bars having a special configuration on two or more surfaces thereof may be accurately formed with-the configurations on the diflerent faces of the bars in proper registration with each other.

My invention also provides a method and .means of this character by which the shaping may be effected through the agency of a rolling mechanism of simple and compact character capable of handling the work rapidly.

A further object is to provide a. method and means which will insure not only the proper and accurate formation of special configurations on the bars, but which will also insure clean sharp corners on the bars..

My invention also provides a method and means whereby the bars may each be acted l upon simultaneously by two pairs of rolls, each. pair of which imparts a special configuration to one or morevfaces of the bars with a relatively short spacing between the two sets of rolls and with a minimum twisting of the blank between therolls.

Other objects'and advantages of my invention will hereinafter appear.

The particular nature of the invention will be best understood by reference to the accompanying drawings, in which I have shown the preferred embodiment thereof and which will now be described, it being premised, however, that various changes can be made inthe details of the method and in the construction and arrangement and combination of the parts employed and the apparatus used, without departing from the spirit and scope ofmy invention as defined in the appended claims.

For the purpose of illustrating my invention, I'have shown means especially adapted .intervals.

Specification of Letterslatent. Patented M 24 1921 a In carrying out my invention, I provide.

a blank such as indicated in cross section in Fig. 7, being of generally rectangular form,

but preferably having its sides concaved or fluted for the purpose which will hereinafter appear.

" This blank may be produced by any suitable means and may be given the fluted or concaved form, shown by means of giving it a finishing pass, such as is indicated in said figure. For convenience in following the subsequent operations upon-this blank, its four corners are designated, respectively, A,,B, A and B,

The blank is then introduced between a pair of rolls 2 and 3, having a pass of the form'shown in Fig. 8. This pass is of generally rectangular form with parallel plain guiding walls which are at an angle of approximately 60 to the longitudinal axes of the rolls and with opposite shaping walls at right angles to the guiding walls. Each of the rolls 2 and 3 is provided with a collar member 4, having on its pass-forming periphery the regularly spaced shaping projections 5, four of such projections being shown on each of these collars. These projections are designed to form the spaced depressions 6, in opposite faces'of the bar, as shown in Fig. 11.

In introducing the blank shown in Fig. 7, into the pass shown in Fig. 8, it is turned approximately 30 in an anticlockwise direction, so that the faces A, B and B, A become the two faces which are acted upon by the shaping walls of the pass shown in F ig. 8.

As the blank issues from the pass shown in Fig. 8 with the depressions 6 formed in two of the opposite faces thereof, as described, it enters a twisting guide 7, (shown in detail in Figs. 12 and 13). This is a fixed guide having an approximately rectangular opening or pass 8, therein and which is arranged to twist the bar passing therethrough in an anticlockwise direction through an angle of approximately 30? As the blank issues from this guide, it enters a roll pass formed by the two rolls 8 and 9. Each of these rolls has a collar member P, which is provided on its pass-forming per phery with a plurality arranged in pairs, as best shown in Fig. 6. Four of these pairs of projections are illustrated and are designed to form the oblong rectangular depressions 12, in the two faces of the blank which were not acted upon by the rolls 2 and 3. Means such as hereinafter described are provided to insure the proper registration of the depressions 12 with the depressions 6.

It will be noted by a comparison of Figs. 8 and 9 that the guiding walls of the pass shown in Fig. 8 are at an angle of approximately 60, to the roll axes measured to one side of the vertical line, while the guiding rolls of the pass shown in Fig. l are at a similar angle to the roll axes measured at the opposite sides of such vertical line, and that each shaping wall ofthe pass shown in F 9 is at an angle of substantially 30 to the guiding wall of the pass shown in Fig. 8, which guides that face of the blank which is acted upon by that particular shaping wall in 9. By reason of this peculiar diagonal! arrangement of these two passes, it will be noted that it is necessary to turn the blank onlyv 30 between the twopairs of rolls 2 and 3, and 8 and 9. This can be effected by a relativel short twisting guide with a minimum istortion of the metal, and thereby enables the two sets of rolls to be placed closely together and inof equally spaced PIOJGCtlOIlS l1,

o rotate in unison with *means of the lock collar tuated.

. tergeared so as to turn in unison in a manner hereinafter described.

After leaving the pass shown in Fig. 9, the blank is preferably passed through a finishing passfsuch as shown at 13 in Fig. 10, the purpose of this pass being to accurately true up the faces and corners of the blank. The blank is then ready to be severed on the dotted lines of the lengths constituting a blank to be used in the manufacture of a spike of special character.

The fluted or concaved surfaces of the blank insures amuch more effective gripping of the blank between the rolls in the pass shown in Figs. 8 and .9, and also insures the corners of the blank being held out in these passes. This is due to the fact that .these initially concaved faces are flattened out in said passes.

It will be readily understood that'various constructions and arrangements of rolls may be provided for carrying out my invention. A preferable arrangement has been illustrated in the drawings and will now be described. In Fig. 1, I have shown a plan and in Fig. 2 an elevation of a rollin mill which embodies the rolls' shown in igs. 8

shown in Fig. 11, each and 9. Each pair of these rolls is suitably positively geared to the upper roll 8. In this manner, the two sets 0 rolls are caused h each other, the guide 7 \being placed intermediate the two sets of rolls, as clearly shown in Figs' land 2.

Each of the rolls 2, 3, 8 and 9 is preferably constructed as follows:

body 17 is provided, such as shown in Fig. 14,'having thereon a seat or seats for the necessary driving gears, a flange 18 at its intermediate portlon,

tion at the opposite side the pass-forming collar 4. sleeve 19, seating against-the collar 4 or 10. It is also provided with a threaded portion 20, for the lock collar 21. The sleeve 19 is keyed to the roll body and is forced up against thepass-forming collar 4, or 10, b

21; The latter is preferably provided with suitable wrench .seats 22, by means of which it may be acand a seating porof said flange for or 10 and for the but 'thisfhas nothing geared to the roll 9 through he large intermediate gear 16, which is alsoformed between the upper rolls.

In order to insure proper registration of theconfigurations imparted by the rolls 8 and 9 with respect to the configurations imparted by the rol1s 2 and 3, I find it desirable to provide some a forming collars 10. or this, purpose, I provide these collars, as shown in Fig. 4, with toothed portions 23, which are designed to engage similar toothed portions on,

the sleeve 19. By backing off the locking collars 21, the sleeve 19 may also be backed shaping passes and with a minimum distortion of the metal. It will also be understood that the roll construction is such as to enable the various forms of shaping collars to. be readily used interchangeably, thus enabling a variety of shapes to be produced on the said mill.
